Letters Patent No. 102,678, dated May 3, 1870.
IMPRO'V'ED SPRING- SEAT.
The Schedule referred to in these Letters Patent: and making part of the saine.
I, DANIEL FREDERICK HAAsz, of' Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an ImprovedSpring Seat for Cars, Ste., of' which the following is a specification.
.Nature and Object 0f the Innen-tion. A My invention consists of a spring seat for cars, ako.,
composed of `a stationary and a movable frame, connected together by springs of peculiar construction, which are attached directly to one of the said frames, and to the other by movable links, so that, while the seat is permitted to yield vertically with the .greatest freedom, any objectionable swaying o1n the same, either laterally or longitudinally, will be prevented.
General Description.`
A is an open,\boxlike frame, which may, in the present instance, be supposed to represent the stationary portion of a railroad-ear seat, and to be secured to the end frames x x of the same in the usual man-` ner.
The movable portion of the seat consists of a frame, B, upon which are arranged strips or slats a, for the support of a cushion or of any suitable covering.
.lhis frame B is connected to the stationary frame byia series of springs, O, which are arranged, in'the present instance, inA sets of twos, one set at each end of the seat, and two sets at each of the opposite sides of the same. 'l
Each spring C consists of a coil, b, wound upon a rod or pin, e, of the frame B, of a projecting end, f, secured directly to the latter, and of an arm or extension, g, which is hung to a movable link, 7 1., of' the frame A.
i The arms q g of each set of springs are inclined in opposite directions, and are consequently opposed to each other, so that, if it were not for the links 71, which permit the outer ends of these arms to yield in opposite directions, the springs would remain perfectly rigid, and would prevent any movement whatever of the frame B.
By the use of theselinks, however, in connection with the above-described springs, arranged at both the sides and ends of the seat, the latter ispermittedto yield vertically with the greatest freedom, while any objectionable swaying of the same, either laterally or j longitudinally, is effeetnally prevented.
It is not absolutely' necessary that Athe springs should be arranged precisely asshovvn in fig.1,"as their number might be increased or diminished; or, instead of being placed in sets of twos, several springs, having their arms g inclined in one direction, might be arranged to act in conjunction with other springs having their larms inclined in an opposite direction, as shown in g. 4.
It is essential, however, in every case, that there sho'uld be at least two springs on each sideand end, oi'fv the seat, opposed'to each other in the manner above,
described.
In some cases the arrangement illustrated in figs. 1 and 2 might be reversed, so as to form a seat such as shown in g. 3, where the frame A becomes the movable portion ofthe seat, and is provided with snitable slats and cushions, 85e., while the frame B is permanently secured 'to the end frames X.
' .It should be'understood, also, that I do not confine myself to the above application of my invention, as it can be adapted to the seats of street-cars and other vehicles, as well as to sofas, lounges, 85e., and it might also be applied to beds.
' Claims. v 1. A spring seat, consisting of frames and B, con-- nected together by springs C, when the latterare at'- tached directly' to one of the said frames, and to the other by links h, all substantially as set forth.
2. The said springs C, arranged at. the sides of the frame, when Athe arms of adjacent springs are inclined in opposite directions, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. i
